Frequently asked questions
Can I join files of different formats?
Yes. They are all converted into one MP3.
How do I change the order?
Use the up and down arrows next to each file.
Is there a limit on files?
No limit is set by us. Very large files can be slow on older phones.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
